问题:我们如何使用NWA规范识别学生性能和增长目标,

回答:简言之,我们不能

NWEA performance and growth norms are nationally representative, and the students who comprised those norming samples came from all 50 states.  Consequently, NWEA norms inform us of how a student's observed MAP performance or growth compares to other similar kids across the nation.  For example, a fifth grader who completes her fall MAP reading assessment with a score of 191 performed at the 13th percentile according to NWEA status norms for the fall.  This means that about 87% of fifth graders across the nation would be expected to produce a higher fall MAP reading score than she did.  Similarly, the NWEA growth norms tell us that this same fifth grader (with the 191 in the fall) would show about six points of growth between fall and spring, on average.  Therefore, if she actually did make six points of growth between fall and spring that year, her growth would be "typical" (or at the 50th percentile, with half showing greater growth and half showing less).

NWEA性能和成长规范很少告诉我们国家熟练度标准。有些州设置高熟练度标准,学生比例相对较低。另一些州设置低标准,学生更多达标。例如马萨诸塞州5年级阅读熟练度标准设置为NWEA规范约53%百分位。全国5年级近一半(47%)可望达到这些标准。但在俄亥俄州,5年级阅读熟练度标准设置为26百分位。约74%的U.S.5年级学生预期会达到更容易阅读标准

状态设置不同的熟练度标准意味着,如果目标涉及满足状态熟练度标准,我们就不能单靠NWA性能和生长规范来确定性能和生长目标假设五年级者, 下降阅读评分191 需要12分增长俄亥俄精通标准,而她需要显示 22点增长满足马萨诸塞精通标准12点目标表示大约84百分位增长,约16%像她这样的学生可以实现(基于平均6分和标准偏差约6分,见NWEA规范发布),而22点目标表示大于99百分位增长。这两个目标都具有挑战性,但第二个目标几乎不可能实现。在两种情况下均非典型(50%)增长都足以满足州熟练度标准
